Upgraded Metal Leveling Knobs with Hot Bed Springs for Ender 3/3 Pro/3 V2 Ender 5/5 Plus/Pro CR-10 CR10S/10S Pro CR 20 and other Voxelab Sovol 3D Printers

These are great for upgrading an ender 3 or an ender 5. Even the CR10 can be upgraded with these. I do like picking up older printers from FB marketplace and upgrading them. I have probably 10 printers that have been upgraded with the springs and knobs. I highly recommend them. The durability is great compared to the factory ones. The fit and finish is good there's no shop edges to any of the knobs. They function a lot better than the factory ones because they're a lot bigger and the grooves allow your hands to not slip. I feel like they're going to be a lot of stronger than the plastic knobs that the factory one comes with. Design is good again comparing with the plastic ones. I think you are able to grip these a lot better.

I was buying it mostly because of springs but it looks goodWorked perfectly for my ender 3, even as regular ender springs are 200mm, they didn’t work well nor me, that’s why I got these 250mm and that’s what I needed. Easy to install and adjust. Looks solid and fit good.

Works as described, happy with overall quality! The red looks nice on my ender 3 pro

The upgraded bed springs for the original Ender 3 V2 are a significant improvement. They are much firmer, which helps the bed stay level longer without needing constant readjustment. Changing out the bed springs is quick and easy, and they have a nice surface finish while remaining durable. However, if you use a bed probe, it's a better idea to use spacers instead.

I received this product for free when I ordered a replacement hot bed. These are a great improvement. They make leveling the bed much easier. I should have printed or purchased something like these years ago.

Works great on my end three pro no issues. The springs are much more sterling than the factory springs that comes with the printer.

Perfect fit for my ender 3

Quality is okay, but it doesn't meet the official quality standard. It will do the job. However, the threading is not as smooth as the official upgrade; it binds. The spring is much longer, but that is not a problem.I received this as a freebie. I was going to replace mine due to age, but ended up returning to the official setup.
